xz: remove XZ_EXTERN and extern from functions
XZ_EXTERN was used to make internal functions static in the preboot code.
However, in other decompressors this hasn't been done. On x86-64, this
makes no difference to the kernel image size.
Omit XZ_EXTERN and let some of the internal functions be extern in the
preboot code. Omitting XZ_EXTERN from include/linux/xz.h fixes warnings
in "make htmldocs" and makes the intradocument links to xz_dec functions
work in Documentation/staging/xz.rst. The alternative would have been to
add "XZ_EXTERN" to c_id_attributes in Documentation/conf.py but omitting
XZ_EXTERN seemed cleaner.
